-=============================================================================================== -Name : LibXmlParser -=============================================================================================== -Project : All Projects -=============================================================================================== -Subject : Progressive XML Parser for all types of XML Files -=============================================================================================== -Author : Stefan Heymann - Eschenweg 3 - 72076 Tübingen - GERMANY - -E-Mail: stefan@destructor.de -URL: www.destructor.de -=============================================================================================== -Source, Legals ("Licence") --------------------------- -The official site to get this parser is http://www.destructor.de/ - -Usage and Distribution of this Source Code is ruled by the -"Destructor.de Source code Licence" (DSL) which comes with this file or -can be downloaded at http://www.destructor.de/ - -IN SHORT: Usage and distribution of this source code is free. - You use it completely on your own risk. - -Postcardware ------------- -If you like this code, please send a postcard of your city to my above address. -=============================================================================================== -!!! All parts of this code which are not finished or not conforming exactly to - the XmlSpec are marked with three exclamation marks - --!- Parts where the parser may be able to detect errors in the document's syntax are - marked with the dash-exlamation mark-dash sequence. -=============================================================================================== -Terminology: ------------- -- Start: Start of a buffer part -- Final: End (last character) of a buffer part -- DTD: Document Type Definition -- DTDc: Document Type Declaration -- XMLSpec: The current W3C XML Recommendation (version 1.0 as of 1998-02-10), Chapter No. -- Cur*: Fields concerning the "Current" part passed back by the "Scan" method -=============================================================================================== -Scanning the XML document -------------------------- -- Create TXmlParser Instance MyXml := TXmlParser.Create; -- Load XML Document MyXml.LoadFromFile (Filename); -- Start Scanning MyXml.StartScan; -- Scan Loop WHILE MyXml.Scan DO -- Test for Part Type CASE MyXml.CurPartType OF -- Handle Parts ... : ;;; -- Handle Parts ... : ;;; -- Handle Parts ... : ;;; - END; -- Destroy MyXml.Free; -=============================================================================================== -Loading the XML document ------------------------- -You can load the XML document from a file with the "LoadFromFile" method. -It is beyond the scope of this parser to perform HTTP or FTP accesses. If you want your -application to handle such requests (URLs), you can load the XML via HTTP or FTP or whatever -protocol and hand over the data buffer using the "LoadFromBuffer" or "SetBuffer" method. -"LoadFromBuffer" loads the internal buffer of TXmlParser with the given null-terminated -string, thereby creating a copy of that buffer. -"SetBuffer" just takes the pointer to another buffer, which means that the given -buffer pointer must be valid while the document is accessed via TXmlParser. -=============================================================================================== -Encodings: ----------- -This XML parser kind of "understands" the following encodings: -- UTF-8 -- ISO-8859-1 -- Windows-1252 - -Any flavor of multi-byte characters (and this includes UTF-16) is not supported. Sorry. - -Every string which has to be passed to the application passes the virtual method -"TranslateEncoding" which translates the string from the current encoding (stored in -"CurEncoding") into the encoding the application wishes to receive. -The "TranslateEncoding" method that is built into TXmlParser assumes that the application -wants to receive Windows ANSI (Windows-1252, about the same as ISO-8859-1) and is able -to convert UTF-8 and ISO-8859-1 encodings. -For other source and target encodings, you will have to override "TranslateEncoding". -=============================================================================================== -Buffer Handling ---------------- -- The document must be loaded completely into a piece of RAM -- All character positions are referenced by PChar pointers -- The TXmlParser instance can either "own" the buffer itself (then, FBufferSize is > 0) - or reference the buffer of another instance or object (then, FBuffersize is 0 and - FBuffer is not NIL) -- The Property DocBuffer passes back a pointer to the first byte of the document. If there - is no document stored (FBuffer is NIL), the DocBuffer returns a pointer to a NULL character. -=============================================================================================== -Whitespace Handling -------------------- -The TXmlParser property "PackSpaces" determines how Whitespace is returned in Text Content: -While PackSpaces is true, all leading and trailing whitespace characters are trimmed of, all -Whitespace is converted to Space #x20 characters and contiguous Whitespace characters are -compressed to one. -If the "Scan" method reports a ptContent part, the application can get the original text -with all whitespace characters by extracting the characters from "CurStart" to "CurFinal". -If the application detects an xml:space attribute, it can set "PackSpaces" accordingly or -use CurStart/CurFinal. -Please note that TXmlParser does _not_ normalize Line Breaks to single LineFeed characters -as the XmlSpec requires (XmlSpec 2.11). -The xml:space attribute is not handled by TXmlParser. This is on behalf of the application. -=============================================================================================== -Non-XML-Conforming ------------------- -TXmlParser does not conform 100 % exactly to the XmlSpec: -- UTF-16 is not supported (XmlSpec 2.2) - (Workaround: Convert UTF-16 to UTF-8 and hand the buffer over to TXmlParser) -- As the parser only works with single byte strings, all Unicode characters > 255 - can currently not be handled correctly. -- Line breaks are not normalized to single Linefeed #x0A characters (XmlSpec 2.11) - (Workaround: The Application can access the text contents on its own [CurStart, CurFinal], - thereby applying every normalization it wishes to) -- The attribute value normalization does not work exactly as defined in the - Second Edition of the XML 1.0 specification. -- See also the code parts marked with three consecutive exclamation marks. These are - parts which are not finished in the current code release. - -This list may be incomplete, so it may grow if I get to know any other points. -As work on the parser proceeds, this list may also shrink. -=============================================================================================== -Things Todo ------------ -- Introduce a new event/callback which is called when there is an unresolvable - entity or character reference -- Support Unicode -- Use Streams instead of reading the whole XML into memory -=============================================================================================== -Change History, Version numbers -------------------------------- -The Date is given in ISO Year-Month-Day (YYYY-MM-DD) order. -Versions are counted from 1.0.0 beginning with the version from 2000-03-16. -Unreleased versions don't get a version number. - -Date Author Version Changes ------------------------------------------------------------------------------------------------ -2000-03-16 HeySt 1.0.0 Start -2000-03-28 HeySt 1.0.1 Initial Publishing of TXmlParser on the destructor.de Web Site -2000-03-30 HeySt 1.0.2 TXmlParser.AnalyzeCData: Call "TranslateEncoding" for CurContent -2000-03-31 HeySt 1.0.3 Deleted the StrPosE function (was not needed anyway) -2000-04-04 HeySt 1.0.4 TDtdElementRec modified: Start/Final for all Elements; - Should be backwards compatible. - AnalyzeDtdc: Set CurPartType to ptDtdc -2000-04-23 HeySt 1.0.5 New class TObjectList.
